Direct-drive and geared electric power plants designed specifically for micro-sized planes. Use the new Microbatics brushless motors with the BLC-1 brushless controller for maximum power on 3D micro planes. The 6mm pager motors are used for smaller planes under 20g using a single 80/90mah li-poly cell. The M-20 and N-20 low voltage (LV) motors are typically used on planes under 35g with a single li-poly cell. The high-voltage M-20 is typically used with two li-poly cells on larger planes up to 2 oz (56g).
